BOLTING-CLOTH CLEANER.

Specification of Letters Patent.

Application filed February 16, 1906. Serial No. 301.486.

To a. whom zit may concern:

Be it known that I, MARCUS J. BARTLETT,

' a citizen of the United States of America, and

a resident of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Bolting-Cloth Cleaners, of which the following is a specification.

The main objects of my invention are to improve the construction and facilitate the movement of the brushing members in bolting-cloth cleaners. I accomplish this object by the device shown in the accompanying drawings, in which- Figure 1 shows the brushin member in elevation seated in a frame whic is shown in section. Fig. 2 is a vertical section of the brushing member. Fig. 3 is a top plan of the same. Fig. 4 is a perspective view of the metal cup. Fig. 5 is an underneath plan of the leather base for the brushes. Fig. 6 is a section of the ball or roller.

In the device shown the frame 1 supports the wire screening or sieve 2 at the bottom and supports the bolting-cloth 3 at the top. The brushing member is formed of a leather base 4, to which is attached a metal cup 5 by means of the fingers 6, which are struck up from the flange 7, as shown in Figs. 2 and 4. The leather base 4 supports the brushes 8, which extend through perforations in said base 4 and are doubled over the wire 9 and further secured by means of the flange 7 when said flange is attached to the base 4. The ball or roller 10 is preferably made hol- -low,so as to permit the same to be made strong and of light weight. The two hollow hemispherical parts of the ball (shown in Fig. 6) are soldered together.

In operation the frame 1 is shifted or agitated, as is usual in flour-bolting devices, by suitable mechanism. (Not shown in the drawings.) This causes the brushing member to move back and forth with its brushes in contact with the bolting-cloth and the ball 10 in contact with the wire screening or sieve and supporting the other parts of the brushing member. The center of gravity of the brushing member is considerably below the point of support of the cup 5 on the ball 10. This keeps the brushing member normally in the balanced upright position, (shown in Fig. 1,) and thus insures proper contact of the brushes with the bolting-cloth.

What I claim as my mvention, and desire to secure by Letters Patent, is

1. A bolting-cloth cleaner, comprising a ball or roller, a socket member supported on said ball or roller and having a flange surrounding the same'below the point of support, and a brushing device mounted on the flange and extending above the socket memher; the center of gravity of said flange and brushing device being below their point of support on said ball or roller.

2. A bolting-cloth cleaner comprising a ,movable brushing member having a socket in its lower face and a ball or roller seated therein; said brushing member having its center of gravity below its point of support on said ball or roller. 1

3. A bolting-cloth cleaner, comprising a ball or roller, a socket member supported on said ball or roller and having a flange surrounding the same below the point of support, a flexible member mounted on said flange and extending beyond the outer edges thereof, and brushes mounted on said flexible member and extending above the socket member; the center of gravity of the parts supported by said ball or roller being below the point of support.

4. A bolting-cloth cleaner comprising a brush-supporting base with brushes thereon, a flanged socket member extending upwardly through the base, and a ball or roller seated in said socket member; the center of gravity of said brush-supporting base and brushes being below their point of support on said ball or roller.

Signed at Chicago this 10th day of February, 1906.
